The application discloses a lossless and efficient data processing method and network interface card based on RMDA, and belongs to the field of data communication of a data center. When a large-scale QP is concurrent in the RMDA, the efficient scheduling processing problem of different QP requests is solved, the lossless request signal, the out-of-order QP request and the waste-free scheduling period are ensured, the scheduling fairness problem of different QPs is effectively solved in combination with congestion control, the blocking of other QP processing by a large message and the excessive number of requests needing to be processed in a single scheduling are avoided, and the head blocking problem is solved.

The invention relates to the technical field of coal sampling systems, in particular to a coal sample caching and transporting device and coal sampling equipment. The coal sample caching and transporting device provided by the invention comprises a fixed outer frame mechanism, a telescopic inner frame structure, a blanking chute, an operating mechanism and a bottom-opening-door type sample barrel mechanism, and the blanking chute is used for guiding collected samples from sampling points into the bottom-opening-door type sample barrel mechanism; the bottom-opening-door type sample barrel mechanism is located under the blanking articulated chute and can be used for collecting samples; when the telescopic inner frame structure can slide relative to the fixed outer frame mechanism to extend out, the bottom-opening-door type sample barrel mechanism is located outside the fixed outer frame mechanism and can conduct unloading, the process and structure of buffering, conveying and unloading of samples can be shortened, the transportation cost is reduced, and the transportation efficiency is improved. Meanwhile, moisture loss caused by overlong exposure time in the transportation process of the coal sample can be avoided, the moisture content of the coal sample is protected, the accuracy and reliability of the final sample during test and analysis are ensured, and the representativeness of the coal sample is ensured.

This invention provides a three-dimensional force data management method and system, relating to the management and communication of three-dimensional force data from tactile sensors. The method quantizes and compresses the X / Y / Z axis amplitudes of each three-dimensional force vector to 10 bits, and separately encodes the X and Y sign bits into 2 bits, forming a compact 32-bit representation of 10+10+10+2 bits. At the transmitting end, continuous three-dimensional force vector arrays are batch-packed into multiple 64-byte communication frames with 32-bit alignment and zero-copy, and then sent. At the receiving end, the three-axis force and direction information is quickly recovered through bitmasking and shifting. Simultaneously, addressing the bus contention problem caused by multiple nodes powering on in parallel, this invention utilizes a unique chip identifier and a hardware counter to generate multi-level random startup delays, enabling staggered initialization and transmission by multiple devices, thereby reducing frame loss and congestion. This invention has the advantages of data compression, fast parsing, low memory and bandwidth consumption, and high stability across multiple nodes, making it suitable for mass production deployment of tactile sensor products using real-time buses such as CAN / CAN-FD.
